How do you round numbers to the nearest tenths?

Answer 1

If the number is 9.159 the 1 is in the tenths place. Look at the number behind it. If the number behind it is greater than or equal to 5 then add one to the number in the tenths place. Since 5 is a number 5 or greater change the 1 to a 2. So your new rounded answer is now 9.2

Answer 2

Ok, say the number was 78.58 you would round it to 78.6 because in 78.58, you can round th .58 to 6.
